Diaqua­bis(2-chloro­benzoato-κO)bis­(N,N-diethyl­nicotinamide-κN (1))nickel(II)

In the monomeric and centrosymmetric title Ni(II) complex, [Ni(C(7)H(4)ClO(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], the Ni(II) ion is located on an inversion center. The asymmetric unit contains one 2-chloro­benzoate ligand, one diethyl­nicotinamide (DENA) ligand and one coordinating water mol­ecule, the ligands being monodentate. The four O atoms in the equatorial plane around the Ni(II) ion form a slightly distorted square-planar arrangement, while the slightly distorted octa­hedral coordination is completed by two N atoms of the DENA ligands in axial positions. The dihedral angle between the benzene ring and the attached carboxyl­ate group is 87.36 (10)°, while the pyridine and benzene rings are oriented at an angle of 41.90 (5)°. In the crystal structure, inter­molecular O—H⋯O hydrogen bonds link the mol­ecules into a two-dimensional network parallel to (10[Image: see text]).
